Inhibitors for aqueous solutions Available to Purchase

Inhibiting acids Hydrochloric acid solution POLYRAD 0515A and 1110A manufactured by Hercules Powder Co. Ltd. have received wide acceptance as corrosion inhibitors for use in hydrochloric acid solution. This acid, in common with other industrial acids, will corrode iron and steel vessels during processing unless they are protected by the presence of a suitable inhibitor. In the case of hydrochloric acid, a number of processes such as metal cleaning, metal pickling and oil well acidifying operations necessitate the use of a soluble, heat‐stable inhibitor in the acid solution.
